To Reproduce

import cadquery

pass

Doing this causes the system to finish with exit code (0xC0000005) or exit code (0xc0000374). Version 2.3.1 and 2.4.0 respectively.

Environment

OS: Windows 10 CadQuery was installed with pip in an empty venv running python 3.11.9

On my side, there is no problem. The OS:

Windows 11 professional 23H2 22631.3447

The Python distribution:

Anaconda3-2023.09-0-Windows-x86_64.exe Python 3.11.5

The Python venv is:

(cqvenv) (base) D:>python Python 3.11.5 | packaged by Anaconda, Inc. | (main, Sep 11 2023, 13:26:23) [MSC v.1916 64 bit (AMD64)] on win32

The CadQuery version: (cqvenv) (base) D:>python Python 3.11.5 | packaged by Anaconda, Inc. | (main, Sep 11 2023, 13:26:23) [MSC v.1916 64 bit (AMD64)] on win32

import cadquery print(cadquery.version) 2.4.0

To reproduce, a test.py file is created, and its content is as following:

import cadquery
pass

@jdegenstein Could this be related to the cadquery-ocp issue that you pinged me about?

While not directly related to the above issue, I ran into a similar problem when using pytest on cadquery 5429f618c6723b47f07ba5394a912e22b0dd5cff on Windows 10 on Python 3.10 with pytest.

Note that a similar script without pytest would work just fine.

Solution was to disable pytest's faulthandler with:

pytest -p no:faulthandler

Hopefully someone else finds this helpful. Note that this issue does not occur on cadquery==v2.4.0.

Thanks @akaszynski , could you paste what is in your env (e.g. conda list or similar)?
